Notes : - add subsection for every component which is important for design, for example:
- Two 100 Mbit Ethernet Transciever Transceiver PHY
- USB PHY
- Programmable Clock Generator
- Oscillators
- eMMCs
- RTC
- FTDI
- ...
- DIP-Switches
- Buttons
- LEDs
|
...
The RTC has an I2C Bus (2-wire SerialInterface) and offers temperature compensated time. The STC-Smart Temperature Compensation is calibrated in the factory and leads to a very high time-accuracy.
RTC intruppt interrupt is connected to MIO0 connected to Bank 500 through pin G6.
...
There are two 100 MBit Extreme Temperature Ethernet provided by Texas Instrumen on the board. Datasheet is provided at TI website. Both PHY's are connected with all I/O Pins to FPGA Bank 34 (VCCIO = 3.3V). PHY Clock 25 MHz source sources is provided from MEMS Oscillator. There is no sharing of signals for the two PHY's.

- Note this list must be only updated, if the document is online on public doc!
- It's semi automatically, so do following
Add new row below first Copy "Page Information Macro(date)" Macro-Preview, Metadata Version number, Author Name and description to the empty row. Important Revision number must be the same as the Wiki document revision number Update Metadata = "Page Information Macro (current-version)" Preview+1 and add Author and change description. --> this point is will be deleted on newer pdf PDF export template - Metadata is only used of compatibility of older exports
